It sounds like you stopped them before they completed joining. So you should have nothing to worry about. If not, you will see them marked as DN from other nodes in the cluster. If you did, they wouldn't have assumed the token ranges and you shouldn't have any issues. You can just copy the original data back (including system tables) and they should assume their own ranges again, and then you can repair to fix any missing replicas.
